OK, here's a different way.  Look, ma, no looping!

  from string import replace
  x=[(1,2),(3,4),(5,6)]
  exec ("d = " + replace (
                     replace (
                         replace (
                             replace (
                                 replace (
                                     replace (
                                         replace (
                                             `x`,
                                             '),', '\001'),
                                         '(', ''),
                                     '[', '{'),
                                 ']', '}'),
                             ',', ':'),
                         '\001', ','),
                     ')}', '}'))
